Enter into His gates with thanksgiving, and into His courts with praise. Be thankful to Him, and bless His name. Psalm 100:4
Thanksgiving: in songs of public worship
Praise: the act of general, public, praise
Thankful: literally, to use (i.e. hold out) the hand; physically, especially to revere or worship (with extended hands—the open one—indicating power, means, direction, etc.)
Bless: adore with bended knees
Thanksgiving is an act of worshiping God. We are to make a point to ENTER His presence with an mind-set and heart-set of worship and adoration with gratitude.
And not only are we to have a mind-set and heart-set, we are to actually BE thankful to God. A humble attitude of worship and joy as we express our outpouring of thankfulness to Almighty God.
Act of Worship.
Not just saying "thanks", but spending time in the presence of God worshiping Him with gratitude for Who He is and all He has done for me.
Who is God?
Thanks Living must include an act of worship of God Almighty.
